how can i build a microphone preamplifier?!

emmm, hi . I need to make a low noise/simple microphone preamp for both electret and dynamic .it would be perfect  if it could be powered with something other than battery , like an adaptor or 1394 port form my computer , mic in jack or anything else. I have an external sound card with +48v phantom power switch (ECHO, Audiofire4). can anybody help me in making any of them (electret and dynamic)? and ... ics that i have now , are a little old.
thanks alot...
